' SPRING-RING.

Specification of Letters Patent.

Patented Dec. 6, 1921.

Application filed April 20, 1920. Serial No. 375,390.

To all whom it may concern:

Be it known that I, CHARLES A. GoozEY, a citizen of the United States, and resident of the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improve-' ments in Spring-Rings, of which the following is a specification.

This invention has reference to so-called spring rings of the class more particularly adapted for use as a connector for chains for personal wear; and has for its object to provide an improvement in rings of this character in which the sliding bolt is provided with a reduced portion into which a portion of the tubing extends for the purpose of retaining the bolt permanently in the tubing and preventing it from becoming forced out and lost even though the ends of the tube become bent out of alinement so that the free end of the bolt fails to enter the opposite end of the tubing.

The nature and advantages of the invention will be better understood when the following detail description is taken in connection with the accompanying drawings, the invention residing in the combination and arrangement of parts as claimed.

In the drawings forming part of this specification, like numerals of reference indicate similar parts in the several views and wherein Figure 1 is a side elevation of my improved ring showing the tubing portion partly broken away and the means for limiting the closing movement of the bolt.

F ig. 2 is an enlarged sectional view showing the swaging method by which the operating projection on the bolt is formed, also showing the inturned end of the tube for preventing the bolt from being forced out of the tubing.

Fig. 3 is a view of the under side of the bolt, showing the hole in the stock formed by swaging or forcing the integral projection out from the opposite side of the bolt.

IVith reference to the drawings, 10 designates the tubular member of the ring, which may be constructed of any suitable material, the body portion of this tubular ringshaped member having a section removed therefrom as at 11 providing an entering mouth or opening into the ring.

In order to provide means for closing this opening I have formed a bolt-member l2 bent or shaped on the arc of a circle, the outwardly-extending portion being slightly smaller in diameter than that portion 13 which is retained in the tube when the bolt is in extended position.

In swaging this bolt so that one portion is of smaller diameter than the other a shoulder ll is formed at the junction, and in order that this shouldered portion shall form a stop to limit the outward or closing movement of this bolt, I have turned the end 15 of the tubular portion inwardly so as to engage this shoulder 14 and limit the movement of the bolt under action of its spring 16, which spring is mounted in the usual way to normally press the bolt to extended position.

In order to provide a manipulating handle or operating member for this bolt, in the old way, the bolt is drilled and a separate and independent pin forced into the hole, which requires a number of delicate operations for so small a device. In order to avoid this construction I have formed a projection or operating member on the outer surface of this bolt by a swaging operation which is that of inserting a swaging tool into the inner side of the bolt as at 17 forcing a portion 18 of the stock outward, which portion is subsequently nicely shaped by the same operation as that required to swage the bolt into form.

My improved construction has a number of advantages over the old type of spring ring of this character; first, by forming'the operating member integral with the bolt adjacent its free end I eliminate the necessity of slotting the tube, which is an expensive and delicate operation; second, I eliminate the old method of drilling and inserting a separate and independent pin to form a projection by which the bolt may be manipulated; third, by forming the bolt with a shoulder 14 and turning the edge of the tube over this shouldered portion I lock the bolt permanently into the tube so that it can not be forced out and lost even though the ends of the tube are sprung or bent out of alinement one with the other so that the free end of the bolt fails to engage the end 19 of the tubular ring.

The device is extremely simple, practical and inexpensive in construction and by its use much of the usual hand labor is eliminated in this construction.

I claim: V A spring ring comprising a tubular ringshaped member having a portion removed to provide an opening thereinto, a bolt mem- 5 her slidable in said tube to close said 0 en ing, an operating projection on said olt adjacent its extending end, said bolt being reduced to provide a stop shoulder, and a portion of said tube extending inwardly to engage said shoulder to limit the closing 10 movement of said bolt.

, In testimony whereof I afiix my signature.

CHARLES A. GOOZEY.
